Before the big scissors were successfully built, Li Mochou had arrived. Feng Mofeng was angry and Li Mochou said something insulting to Huang Yaoshi, and fought with Li Mochou. Li Mochou's robe was burned and left in a hurry. Zhou Botong went to the Valley of Unrequited Love to make a big fuss, Gongsun Lue persuaded Xiaolongnv to marry her father Gongsunzhi. Yang Guo learned from the fool's mouth that his father's death was related to Huang Rong and Guo Jing and determined to avenge him. King Jinlun brought Yang to see the four princes, Kublai Khan, and Kublai Khan introduced to Yang Guo the four masters, Xiaoxiangzi, Nemo, Yin Kexi, and Ma Guangzuo. During the meeting, the masters competed secretly, and Zhou Botong went to the yurt to make trouble.

When Yang Guo and Xiaolongnv met Kublai, Yang Guo went to Xiangyang at Kublai's request, waiting for an opportunity to assassinate Guo Jing. The brothers of the Wu family like Guo Fu, and they came to help Guo Jing shoucheng to see what his sons are worried about. Yang Guo and Xiaolongnv came to Guo Jing. Huang Rong suspected that Yang Guo had a purpose and asked Guo Jing to beware of Yang Guo. In the middle of the night, Yang Guo attacked, but Guo Jing suddenly woke up, thinking that Yang Guo had lost his mind and lost his true energy to Yang Guo. The next day the Mongolian army attacked the city, and Guo Jing went out to fight.

Guo Jing risked his death to rescue the soldiers from the city and broke into the enemy camp alone. However, because his true energy was not enough, Yang Guo was moved by Guo Jingzhi's kindness and righteousness. He shot the arrow and forced the King of the Golden Wheel to rescue Guo Jing. In order to win Guo Fu's heart, the Wu family brothers stabbed Kublai Khan in private, but were bound by him. Kublai told Guo Jing to go to the Mongolian military camp to retrieve the Wu family brothers. Huang Rong asked Yang Guo to go with Guo Jing. Zhao Zhijing and Yin Zhiping also came to Xiangyang to help defend the city. When they saw the little dragon girl, Yin Zhiping was flustered.

Huang Rong confessed to Xiaolongnv that she knew that Yang Guo and Xiaolongnv wanted to assassinate Guo Jing, and Xiaolongnv told Yang Guozhongqing's flower poison, and Huang Rong promised to use her first level to change the antidote for Yang Guo after giving birth. The Mongolian military camp, the King of the Golden Wheel, and others besieged Guo Jing. Guo Jing's heroic temperament and sincere care for Yang Guo at the critical moment of life and death completely conquered Yang Guo. Yang Guo once again violated his original intention and rescued him. The two rode their horses back to Xiangyang, and Huo Du sent a letter of challenge from King Jinlun Fa.

Yang Guo said goodbye to Shendiao and left the cave. He heard Wu Santong cry, and it turned out that the Wu family brothers were going to fight to the death for Guo Fu. Yang Guo agreed to Wu Santong to persuade the Wu family brothers to kill each other. Yang Guo deliberately urged the Wu family brothers to give up and lied about having a marriage contract with Fu, but Xiaolongnv heard this, and Xiaolongnv left sadly. The Wu brothers were shot by Li Mochou's poison, and Yang Guo was in a coma by taking drugs for the Wu brothers. Zhao Zhijing threatened Yin Zhiping and told him about his rape of Xiaolongnv, but he was heard by Xiaolongnv and Guo Fu outside the window.

After the Wu family brothers figured it out, they no longer obsessed with Guo Fu, and volunteered to follow Wu's three links and Tianzhu monk to the Unfeeling Valley to find the antidote for Yang Guo. Zhu Ziliu and Tianzhu monk were caught by mistake. Guo Fu and Wan Yanping were caught by Gongsunzhi, and Yelvqi rescued Guo Fu and worked with Li Mochou and Huang Rong to drive away Gongsunzhi. Yang Guo took Xiaolongnv and Guo Xiang back to the ancient tomb. Xiaolongnv put on the wedding gown left by the grandmother's grandmother and married Yang Guo. Kublai Khan blamed King Golden Wheel for his failures several times. King King Golden Wheel resigned as a national teacher and returned to Tibet to practice. Huo Du cleverly made up his words and returned to King Golden Wheel.

Yang Guo became siblings with Lu Wushuang and Cheng Ying, passed the Jade Girl Heart Sutra to them, and then left quietly. Yang came to Jianzhong and saw the god sculpture, who accompany Yang Guo to practice swordsmanship, and Yang Guo took the god sculpture down the mountain and went to the South Sea to wait for the little dragon girl. Guo Jing and Huang Rong were the masters and married Guo Fu to Yeluqi, and the Wu family brothers married Yeluyan and Wanyanping respectively. Yang Guojiu waited for the little dragon girl to be unsuccessful, and returned to the Central Plains, secretly acting as a hero. Fifteen years later, King Jinlun returned to the Mongolian military camp. Huo Du pretends to be He Shi I lurking in the Beggar Gang, waiting for an opportunity.

Huang Rong and others rushed to the Valley of Unrequited Love and saw the King of the Golden Wheel but did not see Guo Xiang. The big eagle rescued Guo Xiang. Huang Rong asked Guo Xiang to take care of the King, and he and everyone climbed down to the bottom of the valley to rescue Yang Guo. The King of the Golden Wheel tricked Guo Xiang to unlock his acupuncture points. The crowd did not find Yang Guo at the bottom of the lake. They climbed back to the top of the cliff and found that Guo Xiang and the King were gone, so they had to return to Xiangyang. Yang Guo and Xiaolongnv climbed the cliff along the rope left by Huang Rong and others. King Jinlun took Guo Xiang to the ancient tomb to steal the Jade Girl's Heart Sutra. Yang Guo and Xiaolongnv returned to Zhongnan Mountain and met Cheng Ying and Lu Wushuang.

Yang Guo found the golden needle left by Guo Xiang, and guessed that the King of the Golden Wheel might be in the ancient tomb. After using the cold jade bed to heal his wounds, the King of the Golden Wheel found the Jiuyin Zhenjing and the Heart Sutra of the Jade Girl. Yang Guo arrived and the King of the Golden Wheel led Guo Xiang to escape. Kublai Khan decided to use Guo Xiang to threaten Guo Jing, and Yang Guo infiltrated the Mongolian military camp. In order to solve the danger in Xiangyang, Huang Yaoshi came up with a plan to raise his salary, and everyone prepared separately. Yang Guo took Xiaolongnv to Xiangyang to help in the battle, and discussed with Guo Jing to rescue Guo Xiang. Guo Fuyue Yang Guo met in the ruins of the south of the city and apologized for what happened 16 years ago.

Xiaolongnv comforted Guo Fu, and everyone untied the knot. King Jinlun refused to threaten Guo Jing with Guo Xiang and decided to invite Guo Jing to compete. Yaoshi Huang arranged for everyone to lure the Mongolian soldiers, entangle the King of the Golden Wheel, and rescue Guo Xiang. Yang Guo rescued Guo Xiang from the high platform, King Jinlun was buried in the flames, and the Mongolian army retreated. Yang Guoyi explained Kublai Khan and made him feel grateful. After Kublai returned home, he fought for the throne, but his vitality was greatly injured and he was unable to invade south. King Golden Wheel of Falun Gong escaped from the flames and entangled Yang Guo in a showdown, but was killed by Yang Guo. Guo Xiang watched Yang Guo and Xiaolong women ride away gradually.
